SPECIFICATION "forming To all whom it may concern; 7 3

Be it known that I, FRANK XV. MIX, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new'and useful Improvements in Cabinet-Locks, of which the following is a specification.

My invention relates to improvements in cabinet-locks, and is especially adapted for lock, looking upward. Fig. 5 is aview of the keeper-plate, and Fig. 6 is a side elevation of the key.

For convenience of description I have and shall refer to the parts as if they were located in the position shown in the drawings; but in use the position of the lock will be inverted, and that which is now the upper end of the bolt will be the lower end, and the keeper will be placed upon the top of the desk, ready to receive the lock-bolt as it is brought downward upon the same.

A represents a swinging bolt pivoted at a, and pressed upon continuallyby the spring I), with a tendency to throw it into its locked position. Upon this bolt is the fence 0, which rests in the opening of the tumblers B, which tumblers are spring-pressed and act upon the fence to hold the bolt in its-locked position, as in other locks employing tumblers and bolts.

0 designates a sliding bolt, which is pressed upward continually by means of the spring d.

Said sliding bolt is provided with a laterally;

extending arm, 6, which, when the desk is locked, enters the slot 72. in the lock-bolt, and thereby prevents the sliding bolt from being forced up ward under the influence of its spring (Z. A slottedhub, D, and cylinder E, Fig. 4, of ordinary construction, are provided for insertion and guidance of the flat key, Fig. 6. By applying the key to the lock and rotating it to lift the tumblers and allow the fence and the bolt to pass fronithe position shown in part of Letters Patent No. 286,327, dated October 9, 1883,

Application filed April 19, 1883. (Model) 7 Fig. 2 to that shown in Fig. l, the arm 0 of the sliding bolt 0 is liberated, and the spring D immediately forces said plate upward from the position shown in Fig. 21:0 that represented in Fig. 1, when the end of this arm will en- 5 5 gage the edge of the swinging boltA and hold it in its unlocked position, as shown in Fig. 1. VVhenthe desk is'closed, the keeper-plate G, Fig. 5, will engage the projecting arm is and force the sliding bolt inward against the power of its spring, when the lock-bolt A will snap into engagement and over the arm 6 of said sliding bolt, thereby holding said bolt within the case. The tumblers B also snap down upon the fence 6 and positively secure the 6 5 lock-bolt in its position for locking. W'hen the desk is again unlocked and opened, the sliding bolt 0 projects again and holds the parts vin their unlocked position until the desk isclosed again. The parts will then be auto matically released, readyto snap into position for locking, and therefore the application of a key is unnecessary. The sliding bolt G may be termed mechanism for holding the lockbolt or parts of the lock in the unlocked positionl Mechanism for this purpose may be readily devised which will not necessarily be in the form of a sliding bolt, and when located at a point inside of the hooked end of the lock bolt, and provided with a projection which extends through the face of the lock-case for engagement with the keep er, to automatically release the parts for locking upon closing the desk will be considered'the equivalent of the sliding bolt 0. 8 5

I have herein shown this look with a long cylindrical case, E, to adapt the lock to be placed upon the side of the rail or edge-piece of the cover; but this look mechanism may be embodied in a mortise-lock with a shorter cy- 9o lindrical case, and I intend to make another application showing such a mortise lock, which is adapted to receive the lock mechanism herein shown and described.

While the lock herein shown is specially 95 adapted for a flat key, it is evident that mechanism having a projection in the face of the lock for releasing the parts for locking may be used iii-locks which do not employa flat key.

I am aware that the following features are 1 no found in the prior art as shown by United States Patents, viz: The combination of swing ing and'hooked lock-bolts provided with a fence and swinging and slotted tumblers, the

tumblers and bolt both having edge faces or talons for engaging the key; the combination of a swinging and hooked lock-bolt, two springs for pressing upon said bolt in opposite directions, a spring-pressed sliding bolt IO for acting upon the hooked end of the lockbolt to hold it in theunlocked position, and for being acted upon by the end of the padlock-shackle, and a set of swinging tumblers, the same being arranged wholly within a pad- I 5 lock-cas and so that the key never can be brought into cont-act with the swinging and hooked lock-bolt, and the combination of a sliding lock-bolt; swinging tumblers, and a latch for holding the bolt in its unlocked po-' sition, an d for being acted upon by the keeperstaple to release said bolt forlocking, the parts being all arranged wholly within the lock-case All of saidprior art ishereby disclaimed.

I claim as my inventiona 2 5 1. The combination of the swinging and hooked lock-bolt having a talon or edge face for being acted upon by the key for throwing the bolt backward out of engagement with the keeper, and also having its hooked end proj ecting from the face of the lock-case, the swinging tumblers and fence for holding said bolt in its position for locking, and mounted so as to be acted upon by the same key which acts upon said lock-bolt, suitable Springs for 3 5 pressing upon said bolt, and tumblers to force them into position forlocking, and the springpressed bolt C orequivalent mechanism, for snapping into engagement with the lock-bolt at a point inside of its hooked end and holdanism also having the projections in the face of the lock-case for being acted upon at apoint ontside of the case to disengage the hooked lock-bolt, substantially as described, and for the purpose specified. 4 5

2. The combination of the spring-pressed swinging lock-bolt A, having a talon or edge face for being acted upon by the key, springpressed sliding bolt 0, having projection 1:,

and the laterally-extending arm e, for engage- 5o ment with the keeper and lock-bolt, respect ively, the arm 0 also acting as a stop to limit the distance which the end It projects, substantial] y as described, and for the purpose specified. 5 5

3. The combination of the spring-pressed swinging lock-bolt A, having a talon or edge face for being acted upon by the key, tuniblers B, pivoted as described, for being acted i upon by thc'same key that moves the bolt backward, spring-pressed sliding bolt G,hav-

ing projection In, and the laterally-extending arm 6,- for engagement with the lock-bolt and keeper, respectively, the arm 6 also acting'as a stop to limit the distance which the end is projects, substantially as described, and for the purpose specified.
